A Description of the North Shore of the Salmon River Mouth
Gonor, Jefferson J.; Giles, Donald E.
"The following observations were made on July 20, 1966, at a low tide of -1.7 feet." (p.1); This is a description of the physical setting and distribution of plant and animal species near the mouth of the Salmon River. Intertidal invertebrates are emphasized. A more marine location is contrasted with a more estuarine site.

The Willamette River Spring Chinook Sport Fishery, 1947
Johnson, Donald R.; Jensen, Christopher
"The Willamette River has the largest runs of spring chinook salmon of any tributary of the Columbia River rising in Oregon. The run to the Willamette is most unique in that the migrating fish pass up the river through Portland, a city of several hundred thousand people, and support a large sport fishery in the metropolitan area. This river is the major tributary of the Columbia west of the Cascade Mountains and joins that river about 100 miles from the sea. Anadromous forms, other than spring chinook frequenting the Willamette, include fall chinook and silver salmon, steelhead, trout, and shad. Spring chinook populations of the Columbia have declined steadily since about 1890 and those of the Willamette have probably done likewise. An investigation is being conducted to assess the causes of the decline in Willamette spring chinook. A study of the spot fishery is part of the program." (From Introduction)

A preliminary report on the Diamond Lake study
Locke, Fred E.; Oregon. Game Commission
"In January 1946 the Oregon State Game Commission authorized a study of Diamond Lake to determine reason for an apparent decline in the size and number of rainbow trout with the object of maintaining a maximum annual yield through proper management." (From Introduction)

A history of the kokanee in Detroit Reservoir
Wetherbee, J. J.; Oregon. State Game Commission
"Kokanee were originally stocked in Detroit Reservoir in 11959. This species was introduced in hopes that it would utilize pelagic zoo plankton and provide a more varied sport fishery. The trout fishery in the reservoir depends primarily on heavy plants of legal-sized rainbow trout, supplemented by stocking fingerling rainbow. As the introduction of the kokanee has been somewhat successful in this fluctuating impoundment, a compilation of all known biological data would be of interest and aid in the future management of this species."
